gnulib-tool: Add options to create hard links.
* pygnulib/GLConfig.py (GLConfig.__init__): Add 'copymode' and
'lcopymode' to the parameter list. Initialize them.
(GLConfig.default): Don't use symbolic or hard links by default.
(GLConfig.checkCopyMode, GLConfig.setCopyMode, GLConfig.resetCopyMode):
New functions to modify and check the method for copying non --local-dir
files.
(GLConfig.checkLCopyMode, GLConfig.setLCopyMode)
(GLConfig.resetLCopyMode): New functions to modify and check the method
for copying --local-dir files.
(GLConfig.checkSymbolic, GLConfig.resetSymbolic, GLConfig.setSymbolic)
(GLConfig.checkLSymbolic, GLConfig.resetLSymbolic)
(GLConfig.setLSymbolic): Remove unused functions. The functionality of
these are now implemented in the *CopyMode() and *LCopyMode() variants.
* pygnulib/GLFileSystem.py (CopyAction.Hardlink): New Enum value to
describe hard links.
(GLFileSystem.shouldLink): Check if hard links should be used.
(GLFileAssistant.add, GLFileAssistant.update): Try to hard link if
enabled. Copy the file if linking fails.
(GLFileAssistant.add_or_update): Remove temporary files unconditionally.
* pygnulib/GLInfo.py (GLInfo.usage): Document new options in the usage
message.
* pygnulib/GLTestDir.py (GLTestDir.execute): Try to hard link if
enabled. Copy the file if linking fails.
* pygnulib/classes.py: Importy the CopyAction Enum.
* pygnulib/constants.py (hardlink): New function based on
symlink_relative.
* pygnulib/main.py (main): Add new options --hardlink and
--local-hardlink. Invoke 'git update-index --refresh' to mitigate the
effects of the hard links on git.
